SCHOOL-DESK.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed January 23, 1915. Serial No. 3,859.

To all whom it may concern:

Be it known that I, LOUIS H. McKnn, a citizen of the United States, residing in the city of Trenton, county of Mercer, State of New Jersey, have invented a new and useful School-Desk, of which the following is a specification.

My invention consists of a school desk having its side standards formed of a double thickness of sheet metal and tongues or lips on the terminals of the double walls of said standards integral therewith, said tongues or lips comparatively approaching, and the member of the desk which is connected With said standards being formed with grooves or channels to receive said tongues or lips, and the latter being adapted to be tightened on the walls of said grooves or channels producing lightness, strength, and inexpensiveness in the construction of the same.

It consists also in forming the seat-support and the desk-top support in similar manner with similar results.

It consists also of novel means for connecting the seat with its support. It consists also of novel means for connecting the back or back rest and the desk-top with their supports respectively.

It consists also of a novel construction of the axis of the folding seat of the desk of double walls, each Wall being formed of interengaging inturned and outturned lugs, there being a plurality of lugs on the double walls on each side of the axis, as will be hereinafter described.

It consists of novel means for supporting the shelf of the desk in position, and adapting the desk proper to be cleaned and the dirt, etc., removed therethrough.

It consists also in providing the desk top with a novel rack for pens, etc.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, as long as they are included in the scope of the claims.

Referring to the drawings.

1 designates the side standards of a school desk, 2 the legs thereof, 8 the supports at the top for the back 4 of the desk, and 5 the arm on which the supports 6 for the folding seat 7 are pivotally-mounted.

Each of the standards, legs, top supports, and arms is formed of a piece of sheet metal made from the blank shown in Fig. 14, which is folded on itself on the median line b?), and finally shaped, the opposed edges of which come together, being seamed or otherwise connected forming said members hollow of a double thickness of walls, and rendering them light, strong and durable and inexpensive.

8 designates side brackets which support the desk top 9, it being noticed that said brackets are each formed of a piece of sheet metal made from the blanks shown in the upper part of said Fig. 14, which are brought together and their opposed edges seamed or secured forming said brackets hollow of a double thickness of walls and rendering them light, strong, durable and inexpensive. The upper ends of said brackets 8 are formed with vertically projecting lips 10 which are adapted to enter the grooves 11 in the under side of the desk top 9, and are spread apart by the inserted rods 12, as wedges which form dovetailed joints for said top and brackets, and so firmly connect the same, as most plainly shown in Fig. 3. Another form of such joints is shown in Figs. 4; and 5, where portions of the lips 13 are bulged apart as at 1%, they being some what resilient so as to tighten against the walls of the groove 15 in the desk top which they enter and slide through, and so are compressed against said walls and held firmly thereon.

The rear of the standards 1 are formed with pressed out sockets 16, and the lower ends of the forward portions of the brackets are formed with depending legs 17 which are adapted to enter said sockets, thus supporting said ends on the standards, it being noticed that the flanges in the front ends of the brackets enter the rear ends of the contiguous portions of the tops 3 of the standards and are wedged therein similar to what is shown in Figs. 3 and 1, the brackets being furtl'iermore secured to said tops by the stirrups 18, which are riveted to and so connected with said tops and enter said brackets where they receive the transverselyextending bolts 19, which are also passed through the sides of the brackets and are retained in position by the nuts '20 forming firm connections for the parts in question. As the pressed or punched outsockets 16 are integral with the rear bends of the double walled standards 1, they are strong and durable and add but little expense to the desk. Then they are filled by the occupation of the legs 17 whereby they cannot be battered-in by the scholars, and the lower edges of the legs are'covered and guarded from contact and made inaccessible to attempt to pry under said ends and raise the legs also by the scholars.

When the riveted stirrups are removed, th e legs may be raised from the sockets, and thus the desk top may be displaced for purposes of repairs, replacement by a new top, packing, shipping or other purposes.

Again as said depending legs 17 are lowered into the socket 16 and rested therein they are so covered that their lower ends present no raw edges, which otherwise would out anything that comes in contact with them, this being prevented by the above construction.

The seat supports 6 are formed each of a piece of metal folded on itself, rendering them hollow producing a double thickness of walls which are light, strong, durable and inexpensive, they also having on their upper ends flanges which are inserted in recesses or grooves in the underside of the seat 7 and wedged or otherwise tightened therein, thus forming dovetailed joints for said seat and supports which provide strong connections for the parts in question.

The upper portion of the arms 5 have segmental lugs 21 struck up thereon, the same being respectively inturned and outturned, and the rear portions of the sides of the seat supports 6 have segmental lugs "2 struck up thereon, centered from the bolts 2-3, said lugs being respectively inturned and outturned, so that the lugs of one member will enter freely the other, the adjacent ends of the arms 5 entering the adjacent ends of the supports 6, forming with said bolts 23, which pass through said arms and supports, the axis or hinge of the seat, erinitting the latter to be raised and lowered, the opposite lugs being adapted to abut at the terminals of the motions of the seat, the stops therefor, it being noticedthatthe outturned lugs on the arms 9 are shorter than those on the supports 6, thus permitting the same to turn in the latter to the required extent.

Caps are placed over the lugs of the supports 6 and retained .by the bolts 23, as coverings and finishes for said lugs.

designates the shelf in the disk proper, the same having on its sides the tenons 26 which enter mortises 27 in the brackets 8 of the desk-top and reston the bases 28 which are punched out and turned down from the material of said brackets in forming said mortises 27, and so provide firm enlarged orwide rests for said tenons 2G and consequently for the shelf as is evicent, said shelf being held laterally in position by the opposite side brackets 8, without necessarily requiring any applied fastenings.

In the shelf at the sides of the tenons are spaces forming the passages 32 which are within the inner sides of the brackets 8, whereby dust, dirt, or other deposits may be swept through said passages, thus cleaning the interior of the desk proper.

The front of the upperportion 3*of the side standards are formed with forwardly projecting lips 29 which are adapted to enter vertical grooves 30 in the rearof the back 4:, and to be spread apart therein by the rod 31, thus forming a dovetailedjoint for said back and standards, which firmly and reliably interlock said members.

On the desk top 9 at the front thereof is therack 33 for pens, pencils, etc., the same having on its forward end the depending flange 3% which is interposed between the front edge of said top and the rear of the seat back 1, and so retained in position. While the standards and supports are made each of a single piece of metal folded on itself, they each may be made ofseparate pieces of metal, secured together, and preserving the double walls of each part. 7

Attention is drawn to the fact that the seat, back and desk-top are formedof wood, and the members 3,6, andSareformed of metal, each of the latter being provided with a plurality of tongues that are spread apart when in the respective groove or recess of the wooden members, whereby the respective wooden and metal members are firmly connected.

The tongues on the seat supports 6 are shown in dotted lines, Fig. 2, but they are similar to those shown in Figs. 3, 4: and 5. On the center of the bolt between the inner walls of the axial ortion of the seat support and adjacent portion of the standard on which said support is pivotally mounted is a washer 35 which serves to space said walls and prevent crushing in of the several walls that form the axis of the seat-support.

Having thus described my invention what I claim asnew and desire to secure by Letters Patent, is

1. In a desk, a support for the back thereof formed of double walls of sheet metal, lips on the terminals of said walls continuous of the latter and integral therewith, and projecting forwardly therefrom, said back having in its rear side a groove adapted to receive said lips, the latter being adapted to be tightened in said groove.

2. In a desk, members formed of double walls of sheet metal, lips on the terminals of said walls, continuous of the latter and integral therewith, and projecting therefrom, and approximately meeting, and a member of the desk adapted to be connected with said walls, said last named member having a groove therein adapted to receive said lips, the latter being adapted to be tightened in said groove.
